Abstract: 518.370. Control of two motors; safety arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 22, 1938, No. 24661. Convention date, Aug. 20, 1937. Class 38 (iii)] Series-connected motors 10, 11, driving respective axles of a vehicle are disconnected in the event of wheel slippage by the opening of contacts of a relay 18, having two opposing coils, one 19 connected in series with a coil 22 across the motor 10, and the other 20 connected in series with a coil 24 across the motor 11. The coils 22, 24 are wound accumulatively on a core 23 which may have an air gap 26. If wheel slippage occurs, say on the axle driven by the motor 10, the voltage across the motor 10 increases and the energization of the coil 19 increases. The energization of the coil 22 also increases and this coil being inductively coupled to the other coil 24, the energization of the other relay coil 20 is .reduced or even reversed. Thus the contacts 18 open to disconnect the motors by de-energizing the contactor 27 and are latched until the controller 15 is moved to its off position. The coils 22, 24 may be tapped to adjust for any voltage inequality of the motors.

Patent GB-487047-A (GB)
Title: Improvements in and relating to fluxing materials for use in electric welding
IPC: B23K35/362
Filed: 1936-09-11
Abstract: The electric welding-flux described and claimed in the parent Specification, i.e. a flux which is substantially free from uncombined iron oxide and from substances which would evolve deleterious amounts of gas during welding and contains about 75-99 per cent of one or more fusible silicates, the balance comprising substantial amounts of a halide, alumina, or both, is made by melting a composition comprising one or more pre-formed silicates or the ingredients thereof, and, when required, the alumina, maintaining the mass in a fused condition for a sufficient time to enable all reactions, if any, to reach completion, and then chilling the melt sufficiently quickly to produce a solid mass having a vitreous lustre upon fracture.  The halide, when used, may be added either before or after the melting.  The average rate of cooling to produce the desired result is generally about 30 DEG  C. per minute and is preferably produced by casting the mass as a relatively thin layer against a cold block or water-cooled plate of metal.  Alternatively, it may be produced, for example, by pouring the mass into liquid such as water.  The preferred melt contains silica, at least one basic constituent such as lime or magnesia, preferably a mixture of lime and magnesia in the proportions of about 3 : 1 by weight, and alumina, which may be added as such or may be present as an impurity in the other constituents.  The lime, magnesia, &c. may be replaced by the corresponding carbonates.  Materials which modify the properties of the weld, e.g. ferromanganese, ferrosilicon, ferrochromium, calcium molybdate, and carbon, may also be present. In an example, 50 lb. of calcium carbonate, 9,4 lb. of magnesium oxide, and 40,5 lb. of silica are fused, quickly chilled, and granulated.  The materials contain sufficient alumina as impurities to give about 5 per cent of alumina in the final composition, and after granulating 1 oz. of fluorspar is added to each pound of the composition.  Other basic materials, e.g. oxides or manganese, titanium, or the alkali metals, may be added to the cooled mass before or after granulating.  When welding with the composition by the submerged arc method described in the parent Specification and in Specification 433,723, the electrode is inserted in the welding flux and the gap between the electrode and the work is bridged by a sliver of graphite or a wad of steel wool.  On the passage of current, the flux fuses and becomes conductive, and the electrode begins to melt and is fed towards the work and moved along the seam, preferably by a mechanical device.

Title: Process for making pure table salt in conjunction with electrolysis of salt solutions
IPC: C01D3/18
Filed: 1923-10-06
Abstract: In the separation of sodium chloride from the caustic soda lyes obtained by the electrolysis of brine by evaporation, the evaporation is interrupted when the specific gravity reaches 1.25-1.3 and the coarse crystals of salt are separated and washed.  The evaporation is then continued to remove the remainder of the salt which is in the form of fine crystals that cannot be washed satisfactorily.  These fine crystals, without washing, are added to fresh liquor to be evaporated, and dissolve in it so that the contained alkali is not lost, and coarse crystals are again separated during the evaporation of this liquor to a specific gravity of 1.25-1.3 as above described. To ensure that the salt separated shall be pure, the brine used for the electrolysis should be purified by adding sodium carbonate (or caustic soda and carbonic acid) and then tri-sodium phosphate.ALSO:In the separation of sodium chloride from the caustic soda lyes obtained by the electrolysis of brine by evaporation, the evaporation is interrupted when the specific gravity reaches 1.25-1.3 and the coarse crystals of salt are separated and washed.  The evaporation is then contained to remove the remainder of the salt which is in the form of fine crystals that cannot be washed satisfactorily.  These fine crystals, without washing, are added to fresh liquor to be evaporated, and dissolve in it so that the contained alkali is not lost, and coarse crystals are again separated during the evaporation of this liquor to a specific gravity of 1.25-1.3 as above described.

Title: Improvements in automatic fire arms
IPC: F41A5/02
Filed: 1925-10-06
Abstract: 240,880. Kiraly, P. von, Lovasz, J., and Schweizerische Industrie Ges. Oct. 6, 1924, [Convention date]. Breech actions, sliding barrel and breech-block. -A gun of the short barrel-recoil type has a boltactuating slide adapted to be retracted relatively to the barrel and breech-bolt by a lever operated by impact towards the end of the recoil of the barrel. As shown in Fig. 1, the bolt-actuating slide 7 is driven back by a lever 26 pivoted on the barrel 1 and adapted to strike a fixed abutment 29. The slide has two inclined surfaces 8, 9, Fig. 6, engaging a stud 10 on the bolt 5 to effect the locking and unlocking rotations. The surfaces are spaced apart so that there is lost motion before the unlocking rotation begins. The end of the unlocking surface 9 is curved to form a recess 12 whereby, after the unlocking movement, a direct blow is given to the bolt, which then recoils freely to open the breech. The slide 7 is held in the rear position until the recoil movement of the bolt is completed by a catch 15 having a tooth 17 adapted to engage a notch 19 in the slide. The catch is released by the bolt 5 engaging a projection 18. When the slide 7 is in the forward position, the catch rises and a bevelled front surface thereon engages the slide, as shown in Fig. 1, and tends to hold it against accidental actuation. When depressed, the catch acts, by an inclined projection 22, on a sliding tooth 23 on the trigger and disengages it from the sear 24, thus acting as an interrupter to ensure single shots and as a safety device to prevent firing until the breech is completely locked. In a modification, Fig. 7, the lever 30 for actuating the slide 7 is pivoted on the fixed casing 3 and is actuated by a shoulder 31 on the barrel. In other modifications, the lever is pivoted on the breech-bolt or on the slide. The Specification as open to inspection under Sect. 91 (3) (a) comprises also (a) a construction in which, to reduce friction during the unlocking, the surface 9 on the slide is formed, as shown in Fig, 8, with a graduadly increasing inclination ; (b) modifications in which the gun has a tilting breech-block, as shown in Figs. 9 or 10. In the form shown in Fig. 9, the unlocking of the breech-block 5 is effected by a lug 12 on the slide striking an unlocking lever R on the block, and the locking is effected by an inclined surface 8 on the slide engaging a corresponding surface on the block. In the construction shown in Fig. 10. the locking and unlocking oscillat:ions of the block 5 are effected bv a projection 8 on the slide 7 engaging projections 12 on the underside of the block; and (c) proportioning the weights of the parts so that the ratio of the weights of the bolt and the slide is 1 : 1.5 to 1.4, and the ratio of the weight of the slide to the weight of the rest of the gun is between 1 : 10 and 1 : 20. This subject-matter does not appear in the Specification as accepted.
